Application filed September 8, 1909. Serial No. 516,723.

To oti whom it may concern:

Be it known that l, Nniiso'n i ANDl-IICHUN, a oitizen of the United States, residing at l ios Augetes, in the county of his Angelos and State o'l? ali't'ornia, have invented new and uselul Improvements in Means t'or looting the interior of Refrigerating Structures, oli whieh tho following is a speritioation.

My invention rotates to a novel refrigerating structm-e that; utilizes a .tluid circulatlug; mrdium lor nntiniiaining, tho temperature of the air within the strut'turo below the tonipcratiu'e ol the outside air, and it is ono of the ohjects ot my invention to pro Yltlil a struoture whereby the temperature therein may he lowered without the uso of iee or othor art'itit'tial retrigtrauts.

A :lfurther ohject is to provide a novel rorigor-ailing strueture that is simple in eonstruetion, highly ellioient in operation, and one in which a circulation ol. air may in maintained in the rrlirig'orating ohaml'ier to prevent humidity therein.

In the aoooniplishmrnt ot the above ohjoets l prelerahly omploy a eontrete roustruotiioih rein'lort'etl if desired, the walls and lltuil being provided with a plurality of eonnroted ohamhrrs designed to promote a rapid and ronstant liquid (irrulation therethrough. The walls of tho strmxture are provided with a suitahlo vrntilalint: means, and the Hlllltllll't is also proridral with a root having means attarhed thereto, whorrlry the evaporation ol the liquid llowing; through tho ohamhers 'tormed in tho walls and lloor may he rradily r-ontrollml. 'lho whole cont-rote structure is inrlosed hy an. outside wooden structure also prorided with a ventilating means, a heat insulating, space being formed try the walls of the two structures. This insulating, spaoo may he titled with a suitahle insulating matorial in the winter months whon the tenqwraturo is exeoedingly low so as to maintain the trinperatxure within the eoneret'o structure higher than that outside.

In tho attarhed drawings forming a part of this spooitication .l iguro .l is a perspective View of my eon'qileto struoturo. Fig". 2- is a sectional plan view of tho structure. Fig. 3 is a, vertioal crosssertion of the structure taken on line 3-3 of .l ig. 5.

Those walls arr: provided with a plurality of vertioall) extruding irrtangjular ronqmrtments or liq-- uid durts ll), separated one from another try moans ot vortiraltv extending welis or liatlles 17. as rloarly shown in the \nlious iews ol' the drawings. The liquid riroulatinn rompartmouts are open at the top as shown in Figs. 3 and l ol the drawings so that they may be readily cleansed whon do sirod and also to permit the evaporation ot. tho water [lowing therellutuigh.

When the wator oompletoly tilts this ohamlmr. it: flows over rornrr partition it) into the nrx! r'halnher downwardly, passing tlll()ll;l'll a trans 'vorsely disposed pipt or conduit 2t) hrnoaih ono oi the windows, lilltllttt lowing upwardly into tho next (:hamher and so on around in tho sanio manne until it has rout plotely travrrsed all tho rhamhrrs in the walls, linally disrhar ring through an outlot pipe 21 that (extends dou'nwuiullw and disrharQjes into a rah-h trap r ia iu 'lhis oatr' h trap connects to a who drical circulating chamber or duct 23 disend of the chamber and empties into a catch basin 26. The conduit 25 has approximately the same fall as conduit 23 fromthe rear to the front end of the structure and 1t empties into trap 26 that is connected to another conduit 2'? which returns the water to the rear end "of the structure into similar traps located at the rear thereof, contmun'ig in this manner until it finally reaches conduit 28 from which it is discharged to a tank (not shown). 7

l1, the above described means it will be observed that a constant liquid circulation will be set up within. the walls and floor of the concrete structure, thereby completely cooling the air within the structure. It will also be observed that by circulating the liquid' through the various chambers in the walls and through the conduits in the floor that the liquid will not absorb or retain the radiated heat of the outside atmosphere.

The root of the concrete structure is preferably formed from wood or similar material, the vertically disposed side and end walls being formed of studding and scaled on the outside thereof by planking. The roof proper consists of the usual rafters 30 attached to the vertically disposed side walls into the form of an ordinary gable roof. T 1e vertically disposed. side walls of the roof construction are provided with a' plurality of ventilating openings 31 each closed by a pivoted. glass frame 32, the openings being disposed at each side of the window openings in the concrete structure as clearly shown inl ig. 4: of the drawings. These pivoted frai'nes are adapted to be swung from one side to the other of the recessed chambers as shown in Fig. 3 of the drawings to prevent the atmosphere within the chamber from becoming excessively humid.

The entire concrete structure or inner house is preferably inclosed within a wooden structureor outer house, the space between the walls insulating the concrete structure from the outside atmosphere. This structure is provided at the front thereof with a door and the side walls are provided with window frames 34. The rear wall of the structure is preferably provided with a latticcd or louver boarded opening 35 as shown in Fig. lot the drawings. I

in excessively cold weather when it is desired to maintain the temperature within the concrete structui'e higher than the outside ten'ipcrature the space between the dust, mineral wool or like materials.

In operation vwater is admitted through pipe 18 until all the chambers or water compartments are filled, the water passing out through conduit. 28 in the floor of the concrete structure, the amount of Water which enters the liquid chambers being slightly greaterithan the amount that is discharged, will maintain a constant liquid circulation throughout the chambers and conduits. When the temperature within the concrete structure becomes too humid from rapid evaporation of the water passing through the liquid chambers, the pivoted window frames may be swung to the inside as illustrated in dotted lines of Fig. 3, thus quickly reducing the humidity within the chamber. By means of the windows in both structures the circulation of air within the concrete chamber and around the same may be quickly and vetliciently controlled.

It will be observed from the foregoing description that I have provided a novel,

refrigerating structure that may be erected in localities where ice is unobtainable, and which will maintain the temperature within the structure sufiiciently cool so as to enable me to keep perishable articles in a complete state of preservation for the -maximum length of time.

Attention is called to the fact that the inner structure or house is of a conductive material, while the outer house is of a non conductive material. This is an advantage because it facilitates the insulation of the inner house by a packing placed in the space between the walls.

On account of the fact that the ends of the ducts 23 are open enables these pipes to be readily cleaned of slimy and earthy mattor which may be carried in the water, and this can be done without necessitating the disconnection of any piping whatever, furthermore, this arrangement is conducive to the flow of air through the ducts which materially increases the rate of evaporation. This is desirable as it tends to reduce the temperature.

l Vhat I claim is 1.- A refrigerating structure, comprising a plurality of inclosing hollow walls forming a refrigerating chamber, said walls being provided with webs forming a% plurality of liquid circulation compartments connected one with the other, a floor for said chamber, said floor being provided with a plurality of liquid circulation ducts there in open at their ends, and open basins connecting said ducts. i 2. A refrigerating house having a floor of heat conductive material and having a plurality of longitudinally disposed ducts walls of the two structures may be filled with an insulatmg material, such as saw formed therein, said duets being open on the t entis of said house, open basins formed on} the end wails of said house adjacent to time ends of said duets and connecting Stlitt duets, said duets: being arranged at, gratin I atued elevations, and .n'ienns for supplying a t refrigerating liquid to said duets. t

In witness that 1 (-ininl the t'm't'gningg' I have hereunto subscribed my name this tsti (lay (it September, 1901). A
